These images (taken by NASA) show the urbanzation of Chandler (the fastest-growing satellite city on the outskirts of Phoenix).

ps. 1- According to NASA: ""Chandler grew from just 3,799 residents in 1950 to 176,581 residents in 2000, based on 10-year census figures." That's an average population growth rate of 8% per year (over a fifty-year period!!!)

Erich Fisher came up with a new great visualization of web data. The maps highlight where people post geo-tagged photos to Flickr (red) from and geo-tagged tweets to Twitter from (blue), or both (white). (via Information Aesthetics)

What I like particularly about this kind of map is the way it unveils urban hierarchy.
